I thought you were, but looking at the pic you posted I figured I was mistaken. You did a awesome job packaging that in there. You cannot tell from head on.I m running mechanical fan also
I wonder if there isn’t a completely different issue. If it can sit and idle and not run hot, then it seems the radiator and fan are moving enough air to maintain temps. If it heats up as you are driving with even better air flow, is it possible that you are running lean? Any dash lights on, curious when you get the gauge on what that will tell you.
No dash lights...and to clarify, it will eventually run hot just at idle, did it yesterday when I was burping the system...seems to very with outside air temps. It's been in the 30's-50's most days I've been tinkering with this
...My temps are sitting at about 1/2 sitting at idle when driving it will rise to 3/4 or slightly higher on the dash.
I kinda like seeing household plumbing products and plenty of either electrical or duct tape on my motor swaps, but that is just me.that hose is one gipsy setup big time if you went 90 degree from throttle body and 45 degree it will match perfectly to air box
and you can use GM OEM coolant hose with no problems i have apsolutnu no clearance problems

UPDATE: suggestions pleaae...
Truck is not HOT. 197 was the best I saw today after to minutes in town, hillls, stop and go. Its 40 degrees out.
Based on that, that temp gauge should be dead from 180-220 (or is it 210?), so why is the temp gauge moving to 3/4?
Not a cause for concern, however the toyota temp sensor and gauge are somehow sensing an overheat and are shutting down my AC system.
I have yet to find the temp gauge on this thing...could it be a bad sensor? Do I just unplug it and run the torque app? Do I replace it with a chevy? Is there a way to calibrate it?
If you are running the Toyota temp sensor, I would be very surprised if it is wired into the Chevy ECU. The Chevy ECU is usually what controls the AC. If you have a Chevy sensor, I have no idea how the Chevy signal, will be interpreted by the Toyota gauge.
whether Toyota or Chevy sensor, the dash gauge is controlled by a single wire directly to the connector behind the glove box. See pin 2 of the IH1 connector
Vortec Swap - Pin Out Sheets
I have received many requests for this sheet. Probably should have done this long ago. These two images will help those taking on this swap to pinout the IH1 and IH2 connectors that are located behind the glovebox and serve as the main connection to the vehicle harness and vortec harness.

Bottom line, you ARE NOT over heating, your AC issues are not related to temp issues, and your only temp issue is an accurate monitoring ability?
Dash gauge calibration
Confirm you have a Toyota sending unit. It will likely either be located in your top radiator hose or on the PS head. Stand at the PS fender, and look at the firewall end of the head. You will either see a plug filling a port to the water jacket, or a Toyota sender.
Coy all on the AC issue...
I found a tempsending unit on the #1 cyl head (DS front behind the alternator)
is there two, you're saying, or a second unit is required, one to PCM and one to gauge? this motor is an '04 5.3 from a tahoe
I would wager that is the factory Chevy sending unit, providing data to the Chevy PCM. (Google search of some kind, could probably confirm). But yes, if you want to use the Toyota dash gauge, you will need two sending units. A Chevy unit feeding the Chevy PCM, and if you want to use the Toyota dash guage, you will need a Toyota unit, sending the signal it is calibrated to receive.
The Chevy PCM would loose its mind if it received a signal from a Toyota sender. Likewise, your dash guage will not be correct, if it is receiving a signal calibrated for a Chevy gauge.
As I have mention in previous post. Pop the glove box out, and follow the wire connected to pin 2, back through the fire wall, and see where the dash signal is coming from.
